The Building America Space Conditioning Standing Technical Committee and Expert Meeting reports identified high relative humidity as one of three issues with the highest technical priority for ensuring comfort in low-load homes. As such, the primary objective of this project is to evaluate factors that can contribute to high relative humidity in a home (variations in internal loads, equipment sizing, and equipment setup) and quantify their relative magnitude of impact on indoor relative humidity. A technical white paper will assess the sensitivity latent and sensible gains have on comfort and recommended system sizing. This will inform R&D needs for future BA/BTO work, provide actionable information to manufacturers on the equipment needs of low-load homes (see related project, Assessing the Market and Space-Conditioning Needs of Low-Load Homes), and provide system design and sizing guidance to contractors.

enVerid Systems will demonstrate modular air treatment systems that use less energy to remove indoor air pollutants, such as carbon dioxide, in order to drive widespread adoption of this technology. This approach could reduce the energy consumption in commercial and public buildings by up to 50%.

This project proposes to design, pilot, and verify air-source, CO2 heat pump water heaters for domestic water heating in small-scale multifamily buildings. A second, significant goal of the project is to enable technology transfer.

To reduce energy use in homes that are becoming tighter, mechanical ventilation is added to maintain Indoor Air Quality (IAQ). Smart ventilation technologies are being developed to minimize the energy impact of mechanical ventilation while simultaneously maintaining IAQ. This project will demonstrate the energy savings associated with a smart ventilation technology through a combination of field testing and simulations. The target is to get close to heat recovery ventilation (HRV) performance at much lower cost and complexity; and greater reliability through smart control of simple exhaust (or supply) fans. The project will also develop recommendations for utility programs, other energy efficiency programs and for codes/standards on how to calculate credits for smart ventilation systems.

Arizona State University will develop efficient and stable white OLEDs that employ a single emissive material. This advancement in OLED technology could lead to building energy use reductions.

This project will research, develop, and demonstrate blue-emitting layers (blue-EML) capable of overcoming the existing device efficiency vs. device stability tradeoff in blue-emitting OLEDs, and enable next-generation stable white OLEDs (WOLEDs).

The University of Michigan, Ann Arbor, will develop new strategies for increasing the lifetime of blue phosphorescent OLEDs (PHOLEDs). Longer-life PHOLEDs could provide notable energy and cost savings.

Steven Winter Associates will develop and test methods for estimating the savings potential for partially or fully sealing these opening using tools common to energy auditors. The costs and benefits of best practice approaches for reducing energy losses through elevator and stairwell vents will be determined. A technical report will also be prepared for building owners, coop board of directors and energy auditors.

RTI International will develop and validate a reliability model and accelerated life testing methodologies to predict the lifetime of integrated solid-state lighting luminaires. By improving testing methods, this project will give additional product information to manufacturers and SSL users who seek to justify higher first cost for SSL products over less efficient lighting technologies.

The University of California, Los Angeles, will develop components for the fabrication of OLEDs with improved energy efficiency and reduced manufacturing cost. This improved OLED technology could lead to lower-cost, more-efficient lighting options being available on the market.

This project researched new phase change materials (PCM) to store thermal energy for wall assemblies, and develop associated software tools. Heat is absorbed or released when the materials change from solid to liquid or vice versa. PCMs absorb thermal energy and they can reduce the need for heating and cooling in some buildings. Their impact is similar to that of adding thermal mass to the building. Unlike air conditioning systems, they require no maintenance. The use of PCMs and associated software tools can contribute to zero net energy commercial buildings by reducing the energy needs of a building through passive design.

The Recipient will develop Transactive Load management (TLM) signals, expressed in the form of proxy prices reflective of current and future grid conditions, and implement software to calculate such signals. These signals will be designed to provide customers sufficient information to optimize their energy costs by managing their demand in response to system needs. The signals will be transported via proven and available protocols and networks for use by projects that will test the efficacy of the TLM signals using the demand response projects awarded under agreement EPC-15-054.

The team will integrate the developed sensing medium into PARCs previously developed flexible hybrid electronics (FHE) peel-and-stick platform that measures humidity, temperature, light, strain, and gases such as carbon monoxide, methane, ammonia, and hydrogen sulfide at an anticipated cost of <$15/node at scale

Pennsylvania State University will develop a way to better understand and predict the occurrence of short circuits in OLED lighting panels, in order to reduce failure rates by means of new, more-informative panel diagnostics, a modeling capability to predict mean time to failure, and new anti-shorting strategies that address the root cause of the problem.

This project will develop an interoperable protocol that can be implemented in all plug-load devices, unhampered by proprietary restrictions which will implement energy reporting to enable plug-load devices to transmit operating information - such as identity, power consumption, and functional state - through a communications network to a central entity. After a communication infrastructure is established for plug-load devices, the data flow can be reversed to send control signals to individual devices. The central management system that this project will demonstrate is well positioned to provide comprehensive control over diverse plug-load devices.

This project is funding the planning, permitting, and preliminary engineering needed for the integration of advanced energy technologies in a disadvantaged community. The design will provide locally generated, GHG-free electricity from community solar and storage to offset electricity consumption of participants who opt in to the AEC. The design will also enable participants to benefit from savings resulting from various onsite Integrated Demand Side Management (IDSM) actions at no up-front cost, including energy efficiency retrofits, demand response, energy management systems, and an energy education and support program. Participants will pay back retrofit costs and cost of capital for solar and storage assets through an on-bill financing mechanism, including a first-of-its-kind virtual net metering (VNEM) tariff across multiple county-owned sites and residential buildings piloted by Los Angeles Community Choice Energy (LACCE). The project has a strong focus on local outreach and engagement to promote community participation in the AEC, as well as robust data evaluation methods facilitated through the LA County Energy Atlas to ensure design and financing features are optimized.
